Amare Stoudemire scored 21 points and Steve Nash added 20 for Phoenix, then sat out the fourth quarter to watch the Suns rout road-weary Detroit 117-91 Sunday night for the Pistons' fifth straight loss.
Nash made 7 of 8 shots and had nine assists. Jason Richardson scored 17 as the Suns (11-3), with six players in double figures, improved to 5-0 at home and tied Atlanta and Orlando for the best record in the young NBA season.
Charlie Villanueva and rookie DaJuan Summers each scored 13 for Detroit. Ben Gordon was in foul trouble and finished with 10 on 3-of-11 shooting.
The Pistons, who lost at Utah in overtime on Saturday night, finished off a winless four-game road trip.
